Giga has full control of your miners. They set the algorithm they set the pool, the owner of the miner has nothing to do and no power to decide what should happen with his equipment!!!
Also everyone who is looking to place miners there and is not US citizen or green card holder, be aware that you need to register a company in the US because it is already considered a permanent place of production and GIGA is cooperating with the IRS and will tell who the owner is when they ask.
Can Giga Watt please confirm if it's true? They should accepted only US citizens for ICO then!
